[Clang][CodeGen] Fix bad codegen when building Clang with latest MSVC (#102681)

Before this PR, when using the latest MSVC `Microsoft (R) C/C++
Optimizing Compiler Version 19.40.33813 for x64` one of the Clang unit
test used to fail: `CodeGenObjC/gnustep2-direct-method.m`, see full
failure log:
[here](https://github.com/llvm/llvm-project/pull/100517#issuecomment-2266269490).

This PR temporarily shuffles around the code to make the MSVC inliner/
optimizer happy and avoid the bug.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.
